White Indicators (LED)

[Rubengta]

I have a question. Since most of the cars nowadays have "white" blinkers which colors orange when activated. Is there a way to get the mapped blinkers in ZModeler to use this effect too?

For GTAIV this was possible using "Surface > Color" in Vertex-mode. But in ZModeler 3 I believe this isn't working anymore.

I hope you understand what I mean.
Anyone who knows how to achieve this?

Thanks in advance!
